Embodiment Construction

[0017] Preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and together with the embodiments of the present invention are used to explain the principle of the present invention, but not to limit the scope of the present invention.

[0018] See figure 1 and figure 2 , The truck brake pad includes a brake drum 1, a mounting disc (not shown), an inner brake pad 2, a brake shoe 3 and a transmission device 4. The truck brake pad belongs to the drum brake, and the brake drum 1 needs to be connected coaxially with the wheel during use, and the brake drum 1 will rotate together with the wheel when the vehicle is running. The inner brake pad 2 is built in the brake drum 1, and the inner brake pad 2 is attached to the inner wall of the brake drum 1 during braking, and the friction between the two produces frictional resistance so that th...

Abstract

The invention relates to a truck brake pad. The truck brake pad comprises a brake drum, an installation disc, an inner brake pad body, a brake shoe and a transmission device. The brake drum is annular, the brake shoe is arc-shaped, one end of the brake shoe is hinged to the installation disc, the inner brake pad body is fixedly connected with the outer side face of the brake shoe, and the inner brake pad body is arranged in the brake drum and forms a gap with the brake drum. The transmission device is movably connected with the brake shoe and can drive the inner brake pad body to make contactwith the brake drum. At least one chip discharging groove is formed in the brake face, facing the brake drum, of the inner brake pad body, a heating cavity and exhaust holes are formed in the brake shoe, one ends of the exhaust holes communicate with the heating cavity, and the other ends communicate with the chip discharging grooves. Compared with the prior art, when the truck brake pad is used for braking, heat generated by friction can be conducted into the heating cavity through the inner brake pad body and the brake shoe to heat air in the heating cavity, and the air is heated to expand and is sprayed out from the exhaust holes towards the chip discharging grooves, so that dust in the chip discharging grooves is blown away.

Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to a truck brake pad. Background technique [0002] Due to the heavy weight and high inertia of trucks, it is much more difficult to brake when driving on the road than cars. And once the truck fails to stop in time, due to the large kinetic energy brought by the heavy weight of the truck, the accident will be far more tragic than that of a car, so the braking system of the truck is very important in vehicle safety. [0003] The current truck brake pads generally use drum brakes. The brake pads are in contact with the brake drum, and the friction between the two creates resistance to stop the truck. However, existing truck brake pads tend to accumulate dust and lack the ability to remove dust. The dust accumulated on the brake pads is likely to adversely affect the braking effect. Contents of the invention [0004] In view of this, it is necessary to provide a truck brake pa...
